[SOLVED] How to create global (second) SKU?

[ЕвгенияСемихова(ИПСемиховаЕ.А.)]

Please tell me how best to organize a global SKU?

Introduction: each seller has their own unique SKU, some use only 6-digit numbers, which in theory gives the possibility of overlap with others.

What I think: organize automatic creation of a unique (systemic) "SKU_Global", or vice versa - create a separate field "Seller_SKU".

Previously, I thought to link to the product ID and use it as a global article number. But after installing ai-elastic, ID generation occurs in a completely random and inconvenient display.

Please tell me how you implement automatic generation of a global SKU in large projects?

The SKU itself in Aimeos may not be unique but in combination with the siteid it is for each vendor (or must be). The product ID is unique and that must be at the end of the product URL to uniquely identify products from all vendors (this is a configuration option to include the ID in the URL).
